A tethered UAV-based emergency communication and support system and method

Abstract

The invention relates to an emergency communication and support system and method based on a tethered unmanned aerial vehicle. The system includes flight platform subsystem, ground control subsystem, photoelectric composite cable and communication terminal; the flight platform subsystem includes unmanned aerial vehicles, which are equipped with communication base stations, base station antennas and video acquisition equipment; The composite cable connects the flight platform subsystem, and controls and communicates with the flight platform subsystem through the photoelectric composite cable; The control subsystem and the flight platform subsystem establish a communication connection. The invention has the technical advantages of long blanking time, no signal blind area, and real-time aerial video acquisition capability, and can be applied to low-cost cluster communication and video support system solutions in the fields of public security, anti-terrorism, high-rise building fire protection, and the like.

Description

technical field [0001] The invention belongs to the field of emergency communication and emergency rescue, and relates to an emergency communication and support system and method based on a tethered unmanned aerial vehicle. It specifically relates to a power supply through a tethered cable to achieve rapid lift-off and continuous flight work. The airborne flight control system realizes functions such as automatic take-off and landing, attitude stability, air maneuvering, and wind-resistant flight. It can carry portable communication base stations. Launched into the air to set up a special network for emergency communications, an emergency communications support system that can carry high-definition cameras into the air to realize video command support. Background technique [0002] The occurrence of natural disasters, major accidents and other events is sudden, and it is necessary to quickly establish a sustainable wireless broadband emergency communication network with a ce...

Problems solved by technology

However, both methods have obvious limitations: the main problem of the tethered balloon is that it takes a long time to inflate and deflate, and it cannot be quickly lifted into the air to work, and it cannot be maneuvered after being lifted into the air; the main problem of the rotary-wing drone is that it can carry After communicating with the base station, the air time is very short and cannot work for a long time
